SEATTLE – If Wednesday's record heat in the Puget Sound area was any indication, we may be in for a major deep freeze this La Nina winter.
Huh?
The high temperature at Sea-Tac Airport Wednesday was 74 degrees. That was four degrees higher than the same day back in 1970.
It also tied the all-time November record, which was set Nov. 4, 1949. What makes that interesting? Just like this year, 1949 was the start of a La Nina winter.
The National Weather Service provided us with this graphic showing what happened after that 74 degree day in 1949.
- In early December, a major arctic outbreak hit, driving temperatures to around the freezing mark.
- In mid-December, another arctic wave kept temperatures below freezing.
- Another one hit just after New Year's Day 1950.
- In mid-January, another arctic freeze.
- The low point came in late January and early February when temperatures fell to around zero degrees.
KING 5 Chief Meteorologist Jeff Renner warns that Wednesday's 74 degree high is no definite indication that we'll have a repeat of what happened in the winter of 1949 – 50, but he says it does give you something to think about.
